RESETTING DEVICE.

Application filed. December 21, 1920. Serial No. 432,312.

To all whom it may concern 7 Be it known that I, SAMUEL G. MoKnowN, a citizen of the United States, residing at Newark, in the county of Essex, State. of New Jersey, have invented certain new and useful Improvements in Resetting Devices, of which the following is a description, reference being had to the accompanying drawing and to the figures of reference marked thereon.

111 starting internal combustion engines wherein dynamo or magneto electric machines areemployed to furnish the spark to ignite the charges within the cylinders,

so called impulse couplings are employed as to cause the electricmachine to periodically rotate at a high speed of rotation irrespective of the speed of rotation of and in timed relationship with the engine shaft. To couple the engine shaft to the shaft of the electric machine two resiliently coupled iovable members and a latch dog to temporarily restrain one of them are provided and the dog is automatically thrown out of operation when the speed of the engine shaft is sufliciently high.

The object of this invention is to provide means whereby this dog may be reset into coifi'pling member engaging position.

Another object is to provide means,-1n devices of this character, to enable the dog to be reset either from the drivers seat or from the front of the engine. 7

A still further object is to so form the device as to make it equally adaptable to right and left hand rotation of the shaft.

Other objects of this invention Wlll appear after reading this specification in connection with the accompanying drawings in which Figure 1 is a view of my resetting device as applied on a coupling plate.

Figure 2 is a top view of the resetting device while."

Figure 3 is a similar view showing the parts thereof in their-operated position,

Figure 1- is a fragmentary bottom view of my invention.

Figure 5 is atop view of a modified form of my invention, and

Figure 6 is :a side .view of the device shown in Figureii.

The invention .is directed to a manually actuated train of devices for resettingor' shifting thelatcli'tng devices of an impulse, lyshift the latching dog to operative posicoupler to operative position. The impulse coupler to which my invention is preferably applied is of the type shown in the patent to Hermann No. 1,318,206, granted October 7, 1919, and which includes briefly a mag neto or dynamo electric machine of any suitable character on which is mounted a plate 1 by means of screws 2. Extending through this plate is a. main shaft 8 upon which is rigidly secured the coupling members 4 and 5 of the impulse coupler. Cooperating with the impulse coupler is a latch dog 6 which is pivoted on a stud 7 mounted on the plate 1, and said dog is spring pressed to its normal operative position by means of a spring 8 surrounding a rod 9 passing through a. lug 10, said spring hearing at one end against the lug and at the other end against the knee of a toggle joint formed by the rod and one arm 11 of a bell crank lever, the other. end of said bell crank lever constituting the latching dog 6'. A pin 12 acts as an abutment for the latching devices when thrown toinoperative position, and the latching dog is held in this inoperative position by means of the spring 8. It is likewise held in operative position by said spring. All the above parts are shown and described in the patent t-oI-Iermann, and have been referred to her-epurely for illustrating one embodiment of an impulse coupler to which my invention may be applied. In said patent, there is disclosed automatic means for throwing these latching devices into operative position. 'The present invention is directed to a manually controlled means designed to be used in place of this automatic means in this particular type of impulse coupler. My improved manually actuated means is normally disconnected from the latching devices soas not to in any way interfere with the automatic throwing out of the latching devices in the manner set forth in said patent. The normal position of the generator is with its shaft parallel with the shaft of the engine. The latching dog swings in a plane'at right angles to the Y axis of the generator. .h Iyinanually operateddevice for throwing the latch into op erative position is preferably of such type that a pull or a'push thereon from the operators seat or from the front of the engine, and which is in a direction substantially parallel with the generator shaft, will readi tion. Automatic means is also provided for restoring the manually controlled devices to normal position when released so that they will not in any Way interfere with the throwing out of the'ljatching devices.

Referring more in detail to the drawings, my improved manually controlled operating means for the latching devices is indicated as a whole as at 16. p c

This device comprises a positioning member 17 provided with fingers 18 and 19 adapted to engage the plate on opposite tacos thereof adjacent the lug through which the rod 9 passes and a securing stud 20 is adapted to pass through the other lug 13 on the plate. The member 17 is retained in place securely by means of lock nuts 21 screw threaded ontothe stud 20 and by means of the fingers l8 and 19' here'inbefore d sti-bedr The member 17-, as in fact is the whole device, is symmetrical with respect to its longitudinal axis and is provided with an additional pair of fingers 22" and 2-3 for engageil'ient with the plate when the dog and resetting device are mounted for opposite (counterclockwise) rotation of the shaft.

Pivotally mounted on the positioning member 17 about a grooved portion olthe' stud 2-0 is an actuating lever 24 provided with two prongs 25 and 26 adapted to .slidably engage two similar prongs 27 and of alongi'tud inally movable tripping member 29 provided with a rod engaging edge 30. A spring Sitsprungbetween the stud 20 and a lu 32struc'k u from the tripping member serves toivrestoretheparts to the position sliownin Figures 1 and 2. Both the lower member 17 and the tripping member 29 are channeled as at 33 a1id 3i and each are provided with struck up cars 35 and respectively toguide the member 29 in its longitudinal.movement; T he chan-' nets are enlarged at 87 and'38 to permit ready assembly of the parts; The lever 24 is'also providedwith a means for enabling assembly thereof witlrthe member 17, these means comprising a channel 39 tern'iinating nge lever. 24 is pro for attachment thereto'o'i cable leading either to the drivers seat or totlre fiont'of the engine or bet-hi- It can be readily seen that a pull. in either direction will cause the member 29 to move longitudinally to trip the dog 6 to latching position.

. In the modified form of my invention,

there are but two' members; One; of these is apositioi ringi Ymelnb'e'i'i 42 provided ivith pairs of fingers 433 and term: a urpose similar. to the finger's 18, 19, and already described and, a slot t5 encompasses the rod 91. Goof-3e tiling with this'niember,

pressed elatloi either direction.

y p therewith,- is the member 46 providedwit two cam curta'ces 4? adaptedto engage fiiid-it the-5 dog upon movement of the member 46 in Attached to and preferably integral with the member 46 is the actuating handle 53. To restore the members tonormal position after the upper member has been shifted, the member l6 is kerfed as at 48, a corresponding bead 49 is formed on the other member and a compressed spring 50 wound about a stud 51 presses the beaded portions into the kerfed portions thus tench ing to align the parts The stud 51 is adapted to pass through the lug 13 or 10 as the -as may be and the whole device is adapted to be retained in place on the plate 1 with thespring 50 under tension by means o1 a nut 52 screw threaded onto the stud.

From the above it will be apparent that I have provided manually controlled actuating means for shifting the latching dog to operative position relative to the coupling members of the'impulse coupler. This man ually controlled 'ctuating means may be operated by either a pull or a push in a direction substantially at right angles to the line of movementof the latching dog, and is there'i'ore readily actuated from the operators seat of an automobile or from in front of the engine. The manually controlled means is automatically returned to its normal position when released, and as it is disconnected fromthe latching devices, the return movement does not in any way' affect the position of the latching devices or prevent the throwing out of the latching devices when the speed of the engine reaches a predetermined point.

It is obvious that: many of the details of construction and the arrangement of the parts may be varied without departing from the spirit of the invention as set forth in the appended claims.

Having thus described my invention, what I claim is:

1. A resetting device comprising a posiber, means thereon adapted to engage and push a member and means to move the tripping memben 2. A. resetting device comprising an immovable positioning member, a tripping member mountedon thetop sideot said positionii'ig member slidable .lOlTgltiKllflltlll) thereon, said positioning member and tripping member beingprcvided with cooperating guides and slots.- s; 'dstrip ng member provided w itlra part Jioted on said positioning member operable nno n movement th of in the orse eral: estrous to enmove the tripping member and a generir dependenti oi all of the previously mentioned members actuated by said tripping member.

In resetting mechanism of the class described, latching devices therefor normally held in inoperative position, manually actuated means for shifting the latching devices to operative position, means for automatically returning said actuating means to normal position when released, said manually actuated means being disconnected from said latching devices When said latching devices are in operative position.
